This interactive scatterplot visualizes the Iris flower dataset, allowing users to select which numeric attributes appear on the X and Y axes via ReactDropdown menus. The plot encodes flower species through a d3.scaleOrdinal color scale applied to circle marks. The visualization is built with React and D3 v7, using d3.scaleLinear for axes, d3.extent for domains, and d3.csv to load the remote dataset. SVG rendering displays axes and marks, with a tooltip via the title element.
